DEVICE FOR CLEANING YARN, 60.

SPECIFICATION forming part of Letters Patent No. 390,323, dated October 2, 1888.

Application filed "May 4,1887.

To all whom may concern:

Be it known that I, HENRY F. \VEsT, of Gloucester City, in the county of Camden and State of New Jersey, have invented a certain new and Improved Device for Cleaning Yarn or other Material, of which the following is a specification.

The object of my invention is to provide a device of simple construction for effectually cleaning yarn or other similar material in its passage from the bobbin to the spool in a spooling or other machine.

My invention consists in mounting upon a plate having an opening of any suitable form two adjust-able plates provided with any de-' sired number of knives, arranged, preferably, at an angle thereto, with either beveled-off or square cutting surfaces or edges,and the plates disposed in such manner that the yarn or other material may be thoroughly cleaned and any fuzz or fine particles accumulating on the surfaces of the knives continually discharged through openings provided in the sides of the adjustable plates, and also through an opening in the baseplate.

My invention will be more fully understood, taken in connection with the accompanying drawings, wherein I have shown the same in a form which has been found practically efficient, and in which Figure 1 is a perspective view of the improved cleaning device and the adjustable guides secured to the baseplate. Fig. 2 is a top or plan view thereof. Fig. 3 is a perspective view of the device with one of the adjustable knife plates removed, and showing stationary guides secured to the respective ends of the baseplate. Fig. 4 is a transverse section on the line 20 m of Fig. 2. Fig. 5 is a side elevation ofso much ofaspooling-machine as will serve to illustrate the application ofmy improved cleaning device thereto, and Fig. 6 is a front elevation thereof.

Referring to the drawings, Ais the metallic plate, of any suitable form, having a central rectangular opening,a, therein, through which the fuzz or fine particles from the yarn or other material removed therefrom by means of the knives, to be hereinafter fully explained, are discharged.

B and B are two vertical plates provided with snpporting'seats b and I), having oblong Serial No. 237,030. (No model.)

slots 22 and Z) therein for admitting screws 0, for holding these plates firmly to the rectangular plate A and permitting of their adjustment, laterally or otherwise, to accommodate any size thread or yarn. In the sides of these plates are provided a series of slots, I)", for the fuzz or other particles from the yarn to pass through. The vertical plates B and B have preferably cast therewith a series of knives, d and d,arranged at acute angles thereto. These knives taper slightly from the top surface of the vertical plates, respectively, in the direction of the center, and the bottom surface of the knives is preferably flush with the surface of the vertical .plates B and B to the center, while the cuttingedges of the knives are either beveled off, as shown in Fig. 1, or square, as shown in Fig. 3, and these knives are preferably arranged, for example, so that a knife of one series at an angle to the vertical plate B will occupy a position between two knives of a series in the vertical plate B.

The advantage obtained by the setting or arranging of the knives so that they will all be at or nearly at an acute angle to the vertical plates is that any fuzz or fine particles continually accumulating on the upper surfaces of the respective knives will be readily and continually discharged therefrom through the rectangular opening a. of the base-plate A and through the slits b' in the sides of the vertical plates B and B, away from the material being cleaned. A

It should be understood that while the series of k nivcs, preferably formed integral with each of the vertical plates, are arranged, as hereinbefore described, for operation so that a series of knives of one plate will occupy a position between a series of knives of the opposite plate, yet, nevertheless, they must not be so arranged or adjusted to the base-plate as to produce tensional friction between the mate rial undergoing the cleaning operation, because if a tensional friction should be present the material would be instantly severed or cut and the device thereby rendered incapable of performing the function designed-that of removing mote fuzz or small partieles'from fibrous material in its passage in a straight course between the series of angular knives formed with the vertical plates.

Centrally to each end of the rectangular ICO plate Ais secured, preferably, a guide, E, having an eye, e,of such construction as to readily permit of the insertion of the thread therethrough in a manner shown, for instance, in Fig. 1. The stem of this guide is screwthreaded for a portion of its length, and is fitted into the plate A, wherein it can be readily adjusted by hand either upward or downward. The advantage of using an ad justable guide, E, is that when the knives become dull the guides may be readily raised or lowered by hand inthe base-plate A without having to remove the vertical plates B and B, containing the series of knives d and (1, until the entire knife-edge surfaces thereof have become ineffective for the performance of their work in the cleaning of the material. While it is true that the plates B and B,being adjustable, may be readily removed for the purpose ofsharpening the knives, yet with the use of adjustable guides much time is saved, because the entire cutting-surface oftheknives can be used up before removing the vertical plates B and B for grinding and sharpening these knives.

In Fig. 3 I have shown another form of guide, E, rigidly or otherwise secured in the base-plate A, which may be used, if desired; but the adjustable guides above described give preference to for the reasons stated.

In Figs. 5 and 6 I have shown sideand front elevations of so much of an ordinary wellknown construction of spoolingmachine as will serve to illustrate the manner of applying my improved cleaning device thereto. In this machine G the cleaning device is secured to a bracket, 9, attached to the crossframe H of the machine.

I is the bobbin, suitably held in the trough 1', supported by the standards of the machine.

j is a double guide attached to the crossframe H.

k is an ordinary device for guiding the yarn or other material onto the spool.

Z is the spool upon which the yarn or thread is wound, held in the U-shaped end of the bracket m, secured to the frame of the machine and in frictional contact with the driving-pulley 0, which has motion imparted to it from any suitable source.

The manner ofapplying my improved cleaning device to the type of spooling-machine illustrated in the drawings will now be briefly explained.

The yarn or thread being passed upward through the guides j from the bobbin I and through the lower adjustable guide E, secured to the rectangular plate A, and between the knives d and dof the vertical plates B and B, and thence through the upper adjustable guide E of the plate A, through the movable guiding device 7t, and onto the spool l, and continuously wound thereon when motion has been communicated to the frictional driving-pulley 0, imparting motion to thespool Z, and revolving the same in a well-understood manner, the fine particles or fuzz from the cleaning off of the yarn or other material by the knives d and d during the operation of the machine and accumulating on the upper surfaces thereof will be continually discharged therefrom through the opening a of the baseplateA or through the openings in the sides of the adj ustable plates B and B, away from the 'material being cleaned by the device above described.

While I have described my invention in a manner which has been found practically efficient,yet, nevertheless,it is manifestly obvious that the same will admit of modifications, and hence I do not wish to be understood aslimiting myself to the use of the precise number of knives shown, as any less or greater number may be used with practical success, and then, again, their shape may be modified somewhat without departing from the spirit of my invention; and hence I crave the right to modify the same in any manner that will give the best results in the more extended practice thereof.

Having thus described the nature and objectsof myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. A yarn-cleaning device consisting of two plates provided with knives arranged so that while the knives of one plate come between those of the other plate the edges of the two sets of knives will not overlap the median line, but approach or stand in substantially the same vertical plane.

2. A yarn-cleaning device consisting of two vertical plates having slits therein and knives in series formed integral therewith and arranged so that a knife in the series ofone plate will occupy a position immediately between two knives in the series of theopposite plate, yet without the edges of the two series of knives overlapping the median line, but approaching or standing in substantially the same vertical plane,su bstantiall y as described.

3. A yarn-cleaning deviceconsisting of two vertical plates having slits therein, and each plate provided with a series of knives arranged at an angle thereto, and seats having slots therein, in combination with a base-plate and means for adjustably securing said plates thereto so that the edges of the two series of knives will not overlap the median'line, but approach or stand in substantially the same vertical plane, substantially as and for the pur posesset forth.

4. A yarn-cleaning device consisting of two vertical plates, each provided with a series of IIO knives,a base-plate having an openingtherein,

slots therein, a base-plate, means for attaching said plates thereto so that the edges of the two sets of knives of said plates will not overlap the median line, but approach or stand in substantially the same vertical plane, and guides in the ends of said base-plate, substantially as and for the purposes set forth.

6. A yarn-cleaning device consisting of two vertical plates having knives disposed at an angle thereto, and with supporting-seats with slots therein, a base-plate with an oblong open mg, means for adjusting said vertical plates thereto so that the edges of the respective knives of said plates will not overlap the median line, but approach or stand in substantially the same vertical plane, and adjustable guides in said base-plate, substantially as and for the purposes set forth.

7. A yarn-cleaning device consisting of two plates having oblong slits therein and knives tapering to the center with beveled-off cuttingedges and supportingseats formed integral with said plates, a base-plate, and means for securing said plates thereto so that the cuttingedges of the knives of said plates will not overlap the median line,but approach or stand in substantially the same vertical plane, substantially as set forth.

8. A yarncleaning device consisting of two vertical plates with oblong slits therein and provided with knives in series disposed at an angle to each plate, supporting-seats secured to each plate with oblong slots therein, and means, as described, for adjustably securing said seats to said baseplate so that the edges of the two sets of knives will not overlap the median line, but approach or stand in sub slantially the same vertical plane.

9. A yarn-cleaning device consisting of two plates with knives in series formed integral therewith and disposed at an angle to each plate, a base-plate, means for supporting and attaching said plates to said base-plate so that the edges of the two series of knives of said plates will not overlap the median line, but approach or stand in substantially the same vertical plane, and adjustable guides in said base-plate, substantially as and for the pur poses set forth.

In witness whereof I have hereunto set my hand in the presence of two subscribing witnesses.
